get_fill_form — Get the form to fill

Advertised by the server during the last successful anonymous check.

Read the form behind a fill code: questions, types, limits and what to do next. Does not use up the code. Ask the person for missing answers, show them everything, and submit only after they say yes.

submit_fill — Submit the answers

Advertised by the server during the last successful anonymous check.

Submit answers with a fill code. One successful use per code, at most 5 attempts. 201-equivalent result has response_id and receipt: tell the person the receipt. On invalid_answers fix the listed fields and call again.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http ai-form-api-fill-mcp https://aiformapi.com/mcp/fill

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add ai-form-api-fill-mcp --url https://aiformapi.com/mcp/fill

Cursor

Merge this server into .cursor/mcp.json in your project, then enable ai-form-api-fill-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "ai-form-api-fill-mcp": {
      "url": "https://aiformapi.com/mcp/fill"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "ai-form-api-fill-mcp": {
      "type": "streamableHttp",
      "url": "https://aiformapi.com/mcp/fill",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start ai-form-api-fill-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "ai-form-api-fill-mcp": {
      "type": "http",
      "url": "https://aiformapi.com/mcp/fill"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http ai-form-api-fill-mcp https://aiformapi.com/mcp/fill

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
